[0003] For example, the integrated fresh-keeping refrigeration unit with publication number CN2619217Y is composed of a compressor, a condenser, a liquid storage tank, a solenoid valve, an expansion valve, an evaporator and a fan. In order to prevent the lubricating oil in the compressor from flowing into the evaporator, an oil-gas separator is added in the high-pressure area, and an oil return bend is added in the low-pressure area to ensure that the unit can work normally. Its appearance is circular, and its condenser and evaporator are also made into circles, which can achieve the largest possible heat exchange area. In addition, it also has the characteristics of low failure rate, high efficiency, easy installation and use, and wide adaptability.
